A 93-L sample of dry air is cooled from 145 oC to -22 oC at a constant pressure of 2.85 atmospheres). What is the final volume?

vlada-n [284]

Answer:

56 L

Explanation:

We're dealing with a gas in this problem. We may, therefore, apply the ideal gas law for this problem:

$pV = nRT$

We now that we have a constant pressure. Besides, R, the ideal gas law constant, is also a constant number. Let's rearrange the equation so that we have all constant variables on the right and all changing variables on the left:

$\frac{V}{T} = \frac{nR}{p} = const$
